[gdal-dev] Question on how to open a raster in HDFS using GDAL

[James McClain]

Hello,

It may not be finding the native HDFS libraries.  Please see the pull
request https://github.com/OSGeo/gdal/pull/714 for build instructions (in
particular, you may need to augment the LD_LIBRARY_PATH environment
variable).

If trouble persists, I would suggest building against Apache Hadoop 2.7.6
or 2.7.7 (both of those are know to work) as an experiment.

Sincerely,
James McClian
